Knowledge is a Right
August 10, 2026
In the center of Berlin, set among the cobblestones of a public square, there is a pane of glass. Look down and you see an underground chamber lined with white shelves. They are empty. There is space for twenty thousand books, but not one volume stands there.
The Bibliothek, or Empty Library Memorial, marks what happened here on the night of May 10, 1933. Members of the German Student Union gathered to feed more than twenty thousand books into a bonfire. These were texts written by Jewish, socialist, and liberal writers whose ideas the new government had deemed “un-German.” The burning was not spontaneous. It was planned and announced weeks in advance. University students and professors carried it out.
A book burning is a claim about knowledge: that a society may decide what its people are allowed to know. The Universal Declaration of Human Rights, adopted in 1948 out of the wreckage those flames foreshadowed, makes the opposite argument. Knowledge is a right, not a permission. Article 19 protects freedom of expression, and it is careful to say the freedom runs both ways. You may share your ideas, and you may seek out and receive the ideas of others — through any medium, across any border. The right to read is the receiving half of free speech.
Article 26 turns to education and asks more of it than a diploma or a trade. Education, the Declaration states, should develop the whole person and teach us to understand people unlike ourselves. Put the two articles together, and you have a portrait of the citizen that self-government depends on: a person who can inform herself, consider different perspectives, and reason her way to her own judgment. A book ban removes more than a book. It shrinks the reader.
The bans almost always arrive in the language of protection. But when the American Library Association tallied the book challenges recorded across the country in 2025, it found that 92 percent came from pressure groups and government officials. Fewer than 3 percent came from an individual parent. A rule that sorts books by who wrote them, or by who lives inside their pages, is doing something other than shielding children. It is deciding whose history gets taught, and whose family a person is allowed to find on a shelf. Deciding what may be read becomes deciding who may be known. A people cannot govern itself well on a record that someone else has trimmed.
Back in the Berlin square, the burning began with books, not bodies. Removing the record made the rest easier; it is hard to stand up for people you were never allowed to read about. The fire was only the loudest way to decide what a society is permitted to know.
That decision does not require fire. It can be made quietly, in daylight, on paper. A complaint form does slowly what a bonfire does in a night.
This month, classrooms across the country fill again. Close to fifty million children attend our nation’s public schools, and the shelves waiting for many of them hold fewer books than they did a year ago. In the 2024–25 school year, PEN America counted 6,870 instances of books pulled from public school libraries and classrooms — more than 3,700 separate titles among them. The books removed most often were written by authors of color, by women, and by LGBTQ writers. The sharpest jump was in nonfiction, banned at roughly twice the previous year’s rate. The history and biography students reach for to understand the world are among the first to go.
Idaho shows what those numbers look like with the force of law behind them. A 2024 law requires any library to move material deemed harmful to minors into an adults-only section within sixty days of a written complaint, or face a lawsuit. Because the law treats any depiction of homosexuality as potentially harmful, it reaches many of the books and writers already disappearing from shelves elsewhere.
The law has fallen hardest on the smallest libraries. The Donnelly Public Library is a single room of about a thousand square feet. It had nowhere to put an adults-only section, so when the law took effect in the summer of 2024, the entire library had to become adults only. Children can no longer walk in without a parent beside them. Within months, circulation fell by nearly half. In Eagle, the library relocated close to two dozen titles. And across the state, librarians who cannot tell where the line falls have started to guess — pulling a book back from a child’s reach rather than risk being on the wrong side of a lawsuit.
None of this looks like a fire. It looks like a biography a curious kid never finds. A history a family never reads at the kitchen table. A lonely teenager who never meets someone like themselves on the page. It is a shelf getting a little emptier, one complaint at a time.
A shelf emptied one complaint at a time can also be filled one book at a time. In Idaho, a group of students, parents, and a public school librarian is challenging the law in court. Neighbors keep writing letters, sitting through board meetings, asking for titles to be put back. This is a community deciding for itself what it will know.
The pane of glass in Berlin was set into the square in 1995, decades after the fire, by people who chose to keep the emptiness visible rather than pave it over. Those shelves are sealed now. They will never hold another book.
Our shelves are not under glass. Not yet. They are still open, still in reach, still ours to fill.
